VIATER-CIRCULATOR COOLING SYSTEM.

Application filed May 16, 1921. Serial No. 470,046.

T o'aZl whom it may concern:

Be it known that we, Vrc'ron G. FORSLUND and Emma WV. FORSLUND, citizens of the United States, ship, in the county of Clay and State of Kansas, have invented new and useful I mprovements in WVater-Circulator Cooling Systems, of which the following 15 a specification, reference being had to the accompanying drawings hereby made a part hereof.

Our invention relates to improvements in water circulator cooling systems, particularly for explosive engines.

The principal, objects are to provide a simplified and improved method of circulating water from the radiator thru the water-jacket and return to the radiator; also an improved system operative at -varying speeds of the engine, the same belng automatic in its operation.

\Ve attain these and other objects which will be apparent from the following description and the illustrations in the accompanying drawings, in which Figure 1 is a view of an elevation partly in section of an engine and radiator with our invention attached;

Fig. 2, a detail view of that portion of the water supply pipe from the radiator to the water jac et, with the position of the attached air intake pipe;

Fig. 3, a vertical sectional view of the means of taking air from the filler cap;

Fig. 4, a view of our improved filler cap on the line le- 1 0f Fig. 3; and

Fig. 5, a sectional detail view of the checkvalve on the line 55 of Fig. 2.

Similar numerals of reference indicate like parts thruout the several views.

The engine is equipped with the usual water-jacket 3 connected with radiator 1 by means of pipe 23 and water suppl pipe 20. Said radiator is provided with filling tube 2 having hand-grip 4. To this tube 2 we add a hollow chamber extension 5, which we preferably make of glass or other transparent material, having cover 6 to which is attached a central tube 8 extending down ward thru opening 10 to the under side of collar' 14 and provided with threads 12 which are engaged by nut 13, by means of which all parts of the cap are held together as one. A gasket 7 and washer 11 are provided for cover 6 and nut 13 respectively, for the usual purpose. Openings 15 extending from the under side of collar l t-up into the hollow chamber in extension 5, serve to admit moist air from theradiator to said chamber. A pipe 16, tapped into the intake manifold at 17, extends therefrom to and fits snugly into the interior of the lower end of tube 8 and extends above the level of the opening into the radiator so, when filling the radiator, the water will not enter such pipe 16; said pipe 16 being provided, near its entrance to the manifold, with a cutoff valve 18 connected with control lever 19 operated from the dash. An opening 9 is provided in tube 8 within the hollow chamber 5 for the admission of moist air rising thru openings 15 from the radiator 1, when the engine pipe from radiator v is running. Within the water-supply pipe 20, near the elbow where it enters the wateracket, we place a check valve 22 connected with air-intake pipe 21 thru which, when theengine is running, outside air is drawninto the water jacket and thence thru the water and up thru openings 15 to said hol-'- low chamber 5, in which a vacuum has been created by the withdrawal therefrom of the moist air as described. The valve 22 being seated so that such air may enter when the engine is running and automatically cut off when the engine stops. This valve is located within pipe 20 to avoid the dan er of its freezing so as not to work free? obvious that the air pipe 21 provided with y. It is manifold. The vacuum thus created in chamber 5 will draw the outside air thru pipe 21, the check-valve 22 being automatically opened thereby, so that the air will pass thru the water in jacket 3 and pipe 23, gathering moisture on the way, and u' thru openings 15 into the hollow cham er 5, above the water line in the radiator, thus renewing the supply of air for an indefinite continuance of the process described' It will readily be seen that the water is kept circulating thru the water-jacket, pipes and radiatormuch more rapidly by means of the same described process, thus keeping it comparatively cool and more effective as a cooling agent; the speed of the engine automatically increasing or diminishing the rapidity of such circulation.

'Some of the advantages of our invention are the cheapness of construction, the fact that our process does not .use up the water in'the radiator, thus avoiding the necessity of more frequent filling thereof; by enclosing the check-valvewithin the water-jacket or connect-ions avoiding the danger of the device becoming inoperative by such valve freezing in col weather, by use of the hollow extension 5 the pipes are located so far above the'water in the radiator and in a practically enclosed chamber as to absolutely avoid the danger of water from the radiator slopping over into said pipes and still leaving ample means for the vapor or steam to freely enter opening 9 and pass thru pipe 16 to the intake-manifold;

. Having thus described our invention, what we claim as new and desire to secure by Let-l .ters Patent is,

tube, a port in the upper portion of said,

tube allowing free communication between said chamber and the interior of the tube, a

port in the base of the extension chamber allowing free communication between the extension chamber and the radiator, and an air check valve located in said water jacket opening inwardly to balance the pressure between the water jacket and said hollow extension chamber.
